uides 5* 'betweeniwhichitt j 2 brought 8 extends diagonally across the' top of.plate 7 and the under side of the blade is in con-v tact with the elevated surface surrounding the hole 7. It will be seen that when the 5 plate 7 is moved so that the hole 7? is closed at bottom by the top of the plate 5, the hole 7 now forms a pocket or cavity of definite dimensions and which will hold a given quantity of glass. The plate 7 is inter- 10 changeable and is readily removable .from its recess in plate 6.; Thus my cut-ofi may be used for articles of different sizes'by merely employing a plate 7 having a cavity of exactly the proper size to receive the requisite quantit of glass. To permit the use of molds of different heights, the plate 5 may, by means of the adjusting nuts 5", be raised and low red to such heights as to barely permit't-he passage of the molds -under the plate. It will also be seen that when the hole 7 in plate 7 is moved out of alincment with the hole through plate and the cavity 7 is filled with glass, now if the plate 7 be moved so thatthe cavity 7 is into alinement with the 'hole through the plate 5 and with the open top of the mold, any excess of glass projecting 'aheve' the top of the plate 7 will be sheared .otf by the joint action of the edge 7" and the blade 8, and that'the charge of glass will instantly drop through the opening in plate ,5.- into the open mold. The downwardly llaf'ringhsidesof the opening 7? prevents the chirge of glass from sticking in the plate.

harmony with the rotation of the moldcarrying table is obtained as follows: Eorme'd upon the plate 6 is a rearwardly projecting arm 6 which carries at 6 a vertic'ally; adjustable stud 9. .Pivoted to the table, as at 10, is an arm 11 arranged to 'swing horizontally upon the table. The iirin' ll carries a vertical bar 12 which is held in jvertical adjustment by .means of-"setscrew 13. This upwardly projecting bar 7 .licsin the circular path of the downwardly projecting stud 9. When, by the rotation of the table, the stud 9 is caught by th"bar li thc plate 6, and with it the shearing, late 7, slide upon the plate 5, and the cha glass; is now sheared ofi'- from the gat "ri ng iron, and the pocket or cavity 7* is filled w th glass. At the. end of this cut the opening into the top of the mold is clear,-a's above described, and the mold is now in exact po-' sition' to receive the charge from the pocket 7'. Y Therelease of the engaged mcmbersf'9 and 12 is etfected as follows: The agm 11 has a downwardly and outwardly projecting1 extension 11 having at its extremity a 00k 111. having at its outer end a hook or stop 14 which lies in the path of the hook 11 on the 3 rm H and is so positioned that; the two 'ihe'shea'ring movement of the plate 7 in Y claim an Secured to the bracket 4 is an arm 14 books come into engagement at the instant.

the cutting off operation is completed. As;

the table continues tor-evolve, the wedgehke action of the rigid hook 14 upon the pivoted hook 11" causes the arm 11 to swing inwardly, thus disengaging the two hooks as well asthe stud 9 and the bar 12. The plate 6 has a rearwardly projecting rod 15 engaged by a compression spring 16 which abuts against lug 5 projectingupwardly from the end of the plate 5. WVhen the arm 11 is tripped, as just described, the spring 16 retracts the lates 6 and 7 to their, original position. T e -outward swing of the'arm 11 is limited by a stop 17 and its inward swing'hy a stop 18. arm 11 pressednormally outward with the parts 6 and 12 in circular alinement but permittin of the arm.

In Fig. 6 I have shown a modification of my shearing device in which, in addition to the fixed blade 8. I employ a movable blade- 20, pivoted at one end, as at 21, to the flanges 5 and at its other end slidalily connected, as at 22, with the plate 6. The two blades be:

ving disposed at an angle to each other, with the opening 7 between the cutting edges,

the cutting operation will be performed by the movement of the plate 6, as above described.

Various'modifications of shears willsuggest themselves to those skilled in the artand I do not, therefore, limit my shears to the specific forms here, by way of illustration described. U 1

Having" described my invention, what I desire to secure by Letters Patent =1.

2. In a device of the described character, a plate having an aperture therethrou'gh, a shear-plate mounted and slidable upon the plate first mentioned and having therethrough a downwardly flaring aperture, the arrangement being such that said flaring aperture may he moved into and out of coincidence with the aperture first mentioned,
